-gwn TO ALL WHOM IT MAY CONOERN:

Be it known that I, JOHN W. mNsEL, ofthe city and county of Peoria, andState of Illinois, have invented a new and improved Mode of Holding andLocking Window-Sash; and] do hereby declare that the following is a fulland exact description thereof, reference being had'to the accompanyingdrawings, and to the letters of reference marked thereon.

The nature of my invention consists in a window-sash holder and lock, soconstructed that it will Asecurely lock a window (either upper or lowersash) at any point desired. It holds the sashV square in the frame, andkeeps it from setting, does not deface the. sash, is constructed withouta spring, is self-acting, and cannot be opened from the outside.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation. l

In constructing my lock, I first make a case, marked E in FigureNo. 1. Ithen make a lever, marked D, with one or more utes, markedffff At thelower end I make a journal, marked H. From journal H, I construct anarm, marked C, projecting toward the face ofthe lock F. I then placeiluted lever D in ease-E, placing the journal H in a hole made in case Efor that purpose, as shown in iig. I. I'then make a bolt, marked B,constructed withan upright shank, marked m. At the outer end of bolt B,I make one or more spurs, s s. On the upper end of shank m, projectingtoward journal H, I construct a weight, A. On the side of the upper endof shank m, I make ajournal, K. This bolt B, Iplaee in case E,puttingjournal K in a hole made for that purpose in case E, as shown byfigs. 1,' 2, 3, and 4. l

Figure 1 represents-my lock with the cover taken oit, and lever D andbolt B thrown back from sash G by means of knob L and shank n, as shownin fig. 4. Y

Figure 2 representsmy lock when iluted lever D and bolt B are operatingon the sash G.

I mortise my lock into the jamb of either side of the window, near themiddle of the window, where the two sashes come together, the lower lockthree inches below the middle of the sash, and the upper loci; threeinches above where the sashes meet. I make a hole in the front ofq thecasing, and insert -the spindle n through the. casing and into the lock.Nothing is left to view but knob L. By turning the knob to the left,lever D isbrought against sash G, and the sash G is forced against theopposite side of the window-frame, thereby holding both sides ofthesash. When the lever D is brought against sash Gr, the weight A on boltB is relieved, and it carries bolt B against the edge of sash G, thesash being at a point where it is desired to lock the window. There is ahole made in the edge ofthe sash G, and bolt B drops into it bythoaetionof weight A, and locks the sash, so that it cannot be moved upordown. The spurs s s, by the weight' of the sash, are forced into thewood at the top or upper side of the hole, and prevent the bolt B frombeing drawn except by slightly lifting the sash with the left hand, andturning the knob to the right withthe right hand. This, by the action ofarm C, lifts weight A and draws bolt B, leaving the sash free to move upor down. v

Figure 3 represents my lock when uted lever D is operating on sash G,and holding it while bolt B is pressing against the sash by means ofweight A, ready to drop into the first hole that presents itself inmoving the sash up or down.

i Figure 4 represents my lock with the cover on, with knob L, andspindle n, and tinted lever D, and bolt B thrown out from sash, andinside of the case E, complete for use. The lock is made either of brassor iron, or both, as shown in the drawings.

What I claim as my invention, and desire to secure by Letters-Patent, isv The combination of the weight A on the bolt B with the arm C on thelever D, operating together, substantally as and for the purpose hereinspecified.

I also claim one or more spurs, s s, on the upper edge of the bolt B, incombination with the mortises in the window-frame, with the saidWeighted bolt and the uted lever D, operating substantially asdescribed.

JOHN W. HANSEL.
